Die Life Cost at 58% chargeable die-wear share: a worked example in wire drawing & rod processing

Here is what the math looks like when conditions slip. We hold every other input steady and drop chargeable die-wear share to 58%, then walk the calculation through step by step. Die life cost is the total tooling-attributable cost of a drawing die over its service life, spread across the pieces it produces to give a true per-piece die cost.

The inputs for this scenario

  • Pieces drawn before die replacement: 100 units (held at the documented default)
  • Drawing cost per piece: 45 $ / unit (held at the documented default)
  • Chargeable die-wear share: 58 % (the input this scenario stresses; the baseline uses 80)
  • Die replacement / regrind cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Die Life Cost cost = quantity × rate × capture factor + fixed cost.
  • Weighted cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Per piece value works out to 28.6 $ / piece at these inputs.
  • Captured value works out to 2,610 $ at these inputs.
  • Fixed adjustment works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where chargeable die-wear share sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to chargeable die-wear share, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a flat wear share across the run; in reality wear accelerates near end of life, so late-run pieces cost more than this average suggests.
